attern Recognition (PR) is the scientific discipline that studies the operation and design of systems that recognize patterns in data (static or dynamic). The course will give the algorithms able to explore many of the PR applications, and the general analytical models able to cope with real world data. We will be focused on the basic concepts, the models and the tools necessary to the comprehension and design of a pattern recognition system. Starting with a conceptual discussion involving the nature and difficulties inherent to the PR problem, we will give the notions of pattern discrimination, decision functions and decision regions, class separability and metrics. Then we will proceed with the study of the feature extraction and feature selection, parametric and non-parametric methods, dimensionality reduction and kernel methods. We will end with the design and assessment of classifiers for pattern recognition.
1. Pattern Discrimination: decision functions and decision regions; class separability metrics; Linear Discriminants (Euclidian and Mahalanobis), and Fisher discriminant.
2. Feature extraction and feature selection; feature ranking; Kruskal Wallis. Data pre-processing (outliers removal, normalization and scaling, missing data)
3. Clustering: Hierarchical and k-means algorithms
4. Parametric Methods: model selection, linear generalized models, mixture models, Bayes Classification, Parameter estimation: likelihood method; Bayes and risk estimation; Maxima A Posteriori (MAP); classifier; Kullback-Leibler divergence
5. Non-parametric methods: density estimation: Parzen windows and K-nearest neighbors.
6. Dimensionality reduction; Principal Component Analysis (PCA); Non-linear methods.
7. Kernel methods: Mercer kernel, Kernel PCA.
8. Classifier assessment sampling, confusion matrix and error probability; ROC curves; Bootstrapping, Boosting

Theoretical classes with detailed presentation, using audiovisual means, of the concepts, principles and fundamental theories and solving of basic practical exercises to illustrate the practical interest of the subject and exemplify its application to real cases.
Theoretical-practical classes where the students solve practical exercises, which require the combination of different theoretical concepts and promote critical reasoning in the presence of more complex problems.
